I intended to direct my ratio comment to Omega not to you. Sep 25 comment Is it right to have negative rates? @Avatar I think the English word you are looking for is ratio. Sep 14 comment Solve $\int \cos^{2n}\theta d\theta$ Your answer is correct. What makes you think it is wrong? Sep 13 comment What's the probability that the other side of the coin is gold? @Deedlit. You are right, the analysis would not work in that case. I did mention in an earlier comment that I'm using the symmetry between silver and gold. Removing the double sided silver coin breaks that symmetry. Sep 13 comment How to prove Cauchy-Schwarz Inequality in $R^3$? Condition on discriminant should be less than or equal to zero? Sep 12 answered absolute value inequality Sep 11 comment What's the probability that the other side of the coin is gold? He says he randomly grabs a coin and sees that the side facing him is X and asks for the probability of the other side being X. Given the symmetry between silver and gold, it is irrelevant what X is. He happened to pick gold. I think my simple analysis is correct, not just the answer. Sep 11 answered What's the probability that the other side of the coin is gold?
